METALLIC WASHTUB.

Specification of Letters Patent.

Application led November 7, 1906.' Serial No. 342,434.

Patented July 14, 1908.

T o all whom it may concern:

Be it known that I, MALCOLM E. GRAY, a citizen of the United States, anda resident of Rochester, in the county of Monroe and State of New York,have invented a new and useful Improvement in Metallic Washtubs andother Like Articles, of which the following is a specification.

This invention relates to metallic wash tubs and other like receptaclesarranged tov receive in clamping engagement `a foreign body such as awringer or other like articles to be applied to the side of the tub orreceptacle in such a way as to clamp the side of the tub or receptaclefirmly between engaging members carried by the wringer.

In metal wash tubs and like articles the side walls are not ofsuflicient thickness to properly engage the clamping members of thewringer, and again the side walls need reinforcing to stand up under thestrain eX- erted in operating the wringer. It is therefore the purposeof my present'invention to provide both a reinforcement forstrengthening the side wall of the tub or like receptacle and at thesame time also a thickening of the wall Where it is to be engaged by thewringer.

One feature of my present invention consists in forming a ocket ordepression in a sheet of metal andp in inclosing such ocket with asecond sheet and in forming a epression in a third sheet of metaladapted to fit over and inclose the depression in such second sheet. Iprefer to corrugate the bottom surface of the first above named sheetand between such first sheet and the second sheet I prefer tol insert aspacing medium com rising a strip of metal bent to and fro. uch spacingmedium may be located between the corrugations in the second sheet whensuch corrugations are made use of. Such spacing strip is of course out`to a width practically equaling the depth of the depression formed inthe iirst above mentioned sheet and is bent to and fro, back and forth,to the desired conformation and then laid edgewise in the pocket formedin the iirst mentioned sheet to sustain the thrust of the wringertending to force the iirst two above mentioned sheets together. Two ormore of such above mentioned sheets may be formed into the roll at thetop or upper edge ofthe tub or receptacle, of which one sheet is theside wall.

In the accompanying drawings I have shown my invention as applied to awash tub and so conformed and arranged in connection therewith as toadapt such tub to receive the ordinary wringer, which may be clamp edthereon inthe usual way.

Such drawings are as follows Figures 1 and 2 show a portion of the sidewall of a tub embodying my invention and as seen from the outside andinside respectively of the tub. Figs. 3 and 4 show in enlarged verticaland horizontal sections the parts seen in Figs. 1 and 2, such sectionstaken along the dotted lines -y and rldyl respectively of Fig. l. Fig. 5is a view of a modified form of my imrovement as seen from the inside ofthe tub.

igs. 6 and 7 show vertical and horizontal sections of the arts seen inFig. 5. Fig. 8 shows in verticail section a modified arrangement andrelation of the parts comprising my invention. Figs. 9, 10 and 11 showmodified details of the means that may be used for securing the partstogether as will be explained.

Similar characters refer to similar parts throughout the several views.

Referring to Figs. 1, 2, 3 and 4, in that form of my inventionillustrated therein, a

1 represents a portion of the side wall of the tub in which there areformed depressions or pockets having the bottom. or outer walls thereofcorrugated, as seen at d, for the purpose of stiening the wall at thebottom of these depressions or pockets. These pockets are so located inthe side wall of the tub and near the upper edge as Ato be roperlyengaged by the clamping mem ers of the wringer. w represents the usualreinforcing wire around which the bead or roll at the upper. edge of thetub is formed. c represents a plate, referably of the same material asthe side wall of the tub, extending over the depression or pocket andclosing the same from the inside of the tub. o represents a plate, alsoof preferably the same material, formed to fit over the depressedportion of the side wall of the tub and on the outside of the tub. Thelates c and b are secured together and to tie side wall of the tub byrivets r passing through suitable holes therefor in such plates and inthe side wall of the tub. e re resents the spacing stri eXtending from te wall of the tub, at the ottom of the depressed portion and between thecorrugations d therein, inwardly to and contacting with the plate c andthus comprising a support for suc plate c and the wall of the with theflanges f1 tub at the depressed portion and operating tol-prevent aforcing together of the plate c and the side wall of the tub at suchdepressed portion.

I prefer to make the pocketsin the side wall of the tub deeper at thetop than at the bottom, as indicated, so that a minimum pressure of theattaching clamps will securely hold the wrin'ger in place and preventits removal from the tub -until such clamps are opened. It will beunderstood that the spacing strap e is eut of a'width varying to fit thevarying distance between the depressed portion of the side wall of thetub and the plate c. The plates c and b may be each of them extendedaround the wire w and thus formed into the finishing bead or roll at theupper edge of the tub.

Referring to Figs. 5, 6 and 7, in the modification of my inventiontherein shown, the outer and inner plates are formed integrally, as seenat f .in such figures, and on the inside of the tub flanges f1vertically disposed and a flange f2 horizontally disposed are arrangedto fit snugly within and engage, on three sides, the side walls of thepocket or depression formed in the wall of the tub. In other respectsthis modification of my invention is the same as that already described,except that the inner plate, or that portion of the plate f lying on theinside of the tub, is not ield or engaged by the retaining rivets r1,-this is more clearly shown in Fig. 5. The fianges f1 and f2 togetherwith the curved formation of the plate f serve to retain the innerportion of the plate f securely in place and f2 thereon entering andengaging the pocket or depression formed in the'side wall of the tub.

It will of course be readily understood that the size of thereinforcement or wringer attachnient is immaterial, likewise also thenumber of such reinforcements which may be formed upon the tub.

Referring now to' Fig. S, which shows a modified arrangement andrelation of the parts comprising my`present invention,-0t represents theside wall of the tub between which and the plate b there is seen apocket formed by a depression, in this instance, in the plate b, whilethe plate b1 has also a depression formed therein htting around and overand thus containing the depression formed in the plate b. Z2 representsthe corruglation which may be formed in the bottom Wal of the depressionin the plate b. e is a spacing strip or medium which may be used equallywell in this modification.

In Fig. 9 a represents a portion of a side wall of a tub, c1 a portionof a reinforcing plate, such reinforcing plate having pressed away fromthe plane thereof and away from the observer a tongue r2 as indicated indotted lines.

Refer now to Figs. 10 and 1l which show vertical sections of thearrangement of the device shown in Fig. 9, and taken along the dottedline rr4-y4 in such figure, a different method of heading down thesecuring rivet being shown in each of such figures. The depressedportion r2 is seen extending through a suitable o ening therefor in theside wall 1y of a tub an( also through a suitable opening therefor inthe plate c2. For rigidly securing the parts together this tongue r2 maybe headed down as seen in Fig. l() or it may be. bent downwardly on theplate c2 as seen at 1' in Fig. l1.

By thus forming a pocket in a sheet or plate of metal and inclosing suchDocket on the open side thereof by a second s ieet and with one of suchsheets comprising the side wall ofthe tub or receptacle, and thenforming a depression in the third sheet to fit over and inclose thedepression in the first mentioned sheet, there'is afforded a cheap andeconomically produced projection and reinforcement for engagement by theclamping members of a wringer or like article. rl`his in many instancesis sufficient to properly support the wringer and support the c ampingmembers thereof but in the case of large tubs and wringers that are usedfor wringing heavy articles I have found it desirable to intrmluee thespacing strip e.

I desire to cal attention to the fact that the side walls of the tub arematerially strengthened by the reinforcing plates at points considerablyremoved from those directly engaged by the clamping members of thewringer, thus serving to strengthen the wall of the tub and support thesame against the strain exerted thereon in using the wringer.

The operation of my improvement is believed to be sufficiently obviousfrom the above description to call for no further explanation herein.
